A line of code I do not understand

[Maximation]

While creating some mods for Minecraft I came across this line of code in the Minecraft "BlockWorkbench.class" file.

return p_149691_1_ == 1 ? this.field_150035_a : (p_149691_1_ == 0 ? Blocks.planks.getBlockTextureFromSide(p_149691_1_) : (p_149691_1_ != 2 && p_149691_1_ != 4 ? this.blockIcon : this.field_150034_b));

Are the ?'s and the :'s standard Java or is it something custom from Minecraft? In either way, what does this do?

Here is the full method where this return statement is positioned in:

/**     * Gets the block's texture. Args: side, meta     */    @SideOnly(Side.CLIENT)    public IIcon getIcon(int p_149691_1_, int p_149691_2_)    {        return p_149691_1_ == 1 ? this.field_150035_a : (p_149691_1_ == 0 ? Blocks.planks.getBlockTextureFromSide(p_149691_1_) : (p_149691_1_ != 2 && p_149691_1_ != 4 ? this.blockIcon : this.field_150034_b));    }

Has anyone made mods for Minecraft before? What mods did you create?

 

Thank you for hopefully another wise lesson

Itis the ternary conditional operator.

 

Its very simple in the way it works.

 

In this example:

r = x > y ? i : n;

r would gain the value of i.

 

you could also write the above example as a if statement:

if(x>y){    r = i;}else{    r=n;}

or:

system.out.println(1>2 ? "No" : "Yes");

would print the string "No"

Thank you very much! It is very simple, but you have to understand it first. Thank you for the clear explanation!

I do not understand what you say.

[ohJey]

I do not understand what you say.

he said whatcha making, is it a mod (for minecraft?)

Aha.. Well, he should definitely learn to formulate his questions better!

[luke_2bossly]

Aha.. Well, you should defiantly learn to read his questions better! Not like there complicated lols

English is not my native language, that is why I do not understand some of your sayings. Also, I do not like "internet language" as it isn't useful and not as understandable as "normal" English.

But if you want to reformulate your question I would be happy to answer it!

That really wasn't "internet language".. Seemed to me that he was simply trying to be cute. Perhaps he likes you in that way?

Urbandictionary.com might help you.... Personally I only use imo, iirc, and lol noticeably online. Anymore more than the mentioned would make me feel dumb.

This kind of statement is called a Ternary Operator also known as no stop what're you doing

 

It is incredibly annoying to read and maintain and one of the core rules is to make code readable and maintainable.

 

For simple assignments it's ok, but the way it's used here is horrible.

The way and reason it's used there is due to obfuscation.

I thought so, but it's quite poorly obfuscated in that case. Just a bit of extra effort to read it.

 

Still, pls no long ternary operators in code, people. pls no pls

I definitely agree with you, it is horrible!

This is just a line of code in the Minecraft Coder Pack.

Oh well..

Yes they cannot deobfuscate certain things. They provide a couple of lookup tables for these (useful for core modding, i.e. intercepting and substituting byte code - XRay and so on).
